An SDR receiver for $20? Yes!
This looks like a lot of fun, and the price is certainly right! It uses the popular (and cheap!) DVB-T Digital TV USB Dongle Stick.
From the video description:
Download it here: http://spench.net/r/USRP_Interfaces
http://twitter.com/spenchdotnetCompatible devices should be: ezcap, Hama nano & Terratec NOXON (get the first two as it has a better tuner – the Elonics 4000, same as FUNcube Dongle, broadest frequency range: 64-1700 MHz).
This all started here (info & code): http://sdr.osmocom.org/trac/wiki/rtl-sdr
My ExtIO plugin also supports all USRPs, the FUNcube Dongle and network streaming using BorIP (see it here: http://www.youtube.com/watch?v=_2PaSeR-4Ck). You can also send the received baseband data over the network to GNU Radio using the UDP Source block.

Whetting my appetite
The weather has been phenomenal this winter, as you all know. Due to Arctic air staying way up north, we’ve had one of the warmer Winters that we’ve had in a while. Who would’ve thought last Halloween, when we had that early snow, that Winter was going to turn out the way it did?
The early warmth and early blooming and budding is playing havoc with my head, though. My nose is all stopped up and my eyes are itchy and watery. Allergies are no fun; but this too shall pass.
So when my friend Rem K6BBQ posted about another video from last year, it’s gotten me all torqued up for portable operating for this coming Spring and Summer outdoor operating season. Shorts and T-shirt weather may not be immediately imminent; but I dare say it’s closer than father away!

Interview:
- Russ and Richard interview Fabian “Fab” Scherschel, co-host of the Linux Outlaws podcast.
- Fab transitioned from Windows to Ubuntu in 2007. The biggest issue was games, but he bought a PlayStation 3 to satisfy that requirement. Minecraft runs well on Linux.
- Fab’s primary motivation for Linux Outlaws was to practice his English.
- Our hosts then discuss Ubuntu, Linux Mint, Canonical and Debian.
- We then talk about software patents from a UK and German perspective.
- Fab is switching his servers from CentOS to Debian, primarily because there is no upgrade from one major release of CentOS to another. He also likes to try different distributions so as to maintain impartiality.
- Fab asks how Linux in the Ham Shack began.
- You can contact Fab via Google Plus.
Feedback:
- LinuxCanuck asks for help accessing links and RSS feeds from the website. Everything seems to be working on this end.
- Phil, AK4RQ, recommends the book ‘The C Programming Language’ by Kernighan and Ritchie, originally published by Prentice Hall in 1978. Thanks, Phil.

Show Notes #078
Introduction:
- Richard says life has been good, lately, except for Linux Mint, but we’ll get into that in a moment. Announcements and feedback are at the end of the show.
Topics:
- Linux Mint Sux!!! (At least, for Richard.)
- Richard’s never-ending quest for a Linux distro that works for him. In the past few days, he’s tried various Debian-based distributions:
- Linux Mint 12, with Gnome 3, MATE, and Cinnamon, but he didn’t like any of them. Too few configuration options for the desktop and gtkpod didn’t work, and that was a deal-breaker.
- Linux Mint Debian Edition (LMDE): one of the CPU cores wasn’t running; fixed that, installed software and updates, but gtkpod didn’t work there, either.
- Crunchbang Linux: too minimalist and too much configuration.
- XFCE on LMDE was close. Richard replaced the Thunar file manager with Nautilus.
- Xubuntu which is Ubuntu with XFCE. It looked good, was configurable, but lacked a few features.
- Kubuntu, which is Ubuntu with KDE. He tried installing it from the live CD, which took 25 minutes to complete. After the reboot, it generated all sorts of hard drive errors. While it’s possible that the hard drive did fail, but Richard blames Kubuntu for causing the problem.
- Richard’s never-ending quest for a Linux distro that works for him. In the past few days, he’s tried various Debian-based distributions:
- Russ discusses OpenMediaVault, an open network attached storage solution.
- It’s an alternative to FreeNAS.
- Debian-based with a simple install process, while FreeNAS is based on FreeBSD.
- Supports many features of FreeNAS, including CIFS/Samba, NFS, FTP, SSH, BitTorrent (via plugin), TFTP, and DAAP (via plugin).
- Russ tried it in a virtual machine, and it installed easily. Once installed, all configuration occurs through the web browser.
- While it’s perhaps not as mature as FreeNAS, it’s also a newer project, so it’s likely to improve. At the moment, Russ prefers FreeNAS, especially v0.7, but OpenMediaVault may very well catch up and surpass FreeNAS.
- Linux Contesting Software revisited. We covered a few in Episode 70, and here are a couple more.
- Bill, W9YA, one of the maintainers of YFKtest, contacted Richard to inform him that YFKtest has had a major facelift, as well as adding a few features and fixing some bugs. It’s available as v 0.0.10 from the subversion repository. Russ downloaded the compiled version. He picked a contest, filename for the log, entered his call sign, mode, and some other information, but he had trouble entering a contact.
- Minos Contest Logging Software is a contest logging suite for VHF and UHF Amateur Radio Contests. The current version is 1.5.4, and is available as a download or via the Subversion repository. It’s a Windows application, and there are directions on the Web site for running the application using WINE. If only they’d simply re-release with Linux-native code. Russ tried it and it does run quite well under WINE. It’s an open source project under the BSD license.
- Allstar Link Node Update: Russ now has an Allstar Link node number assigned, 28357. Allstar Link offers several packages: Limey Linux, ACID CentOS or Pickle Linux (for the BeagleBoard). Russ has been trying to get the ACiD version running on his LMDE machine so he can use it with his existing Asterisk installation. Meanwhile, Russ has his Echolink station working, node 54711.
Feedback:
- We received a voice comment from Ed, KB4VWA, who’s having trouble with some MFJ TNCs he recently bought at the Dalton, GA hamfest. Richard responds, though he’s had the least experience with MFJ TNCs. There are several possibilities: wrong on-air baud rate, bad connection, wrong dip switch settings, or poor or filtered audio into the TNC. Try using the jack on the back of the radio for the audio. Maybe the radio is not exactly on frequency?
Announcements:
- The OGG and MP3 feeds for the LHS Music and LHS Up All Night audio streams from the LHS web site have new links, so check your settings. The live streaming feed is mp3, so it works everywhere.
- The wAVEgUIDES podcast joins the Black Sparrow Media network! Visit blacksparrowmedia.net/join/ if you’d like to add your podcast to the Black Sparrow Media network.
- Episode renumbering: Ever since naming episodes 18a and 19a, it’s been bugging Russ, so they were renumbered to eliminate the letter suffixes.
- LHS hopes to attend the 2012 Dayton Hamvention in May. Please donate to the cause to help make that happen!

Not a happy coincidence
Through a post on the nogaqrp e-mail reflector, I learned from Jim W4QO that the QRP ARCI Spring QSO Party will be the weekend of April 7th and 8th.
Holy Saturday and Easter Sunday – Ouch with a capital “O”.
Sunday participation will be just about impossible. I am not totally sure at this moment in time, but we usually spend the day with Marianne’s brother and his wife. There may be a chance for an hour or two between Sunday morning Church services and leaving for there.
Saturday is going to be extremely hard also, as that is Holy Saturday which is generally a busy day at our household. Maybe, if I am lucky, an hour or two in the late afternoon.
I am going to have to really try to mazimize my QSO rate for the miniscule amount of time that I will be on the air.
